Coverage Area
    Not unlike HID lighting, the coverage of your LED grow lights will depend upon the mounting height of the bar.  
Your mounting height will be determined by the light requirements of your plants as well as your plant's access to
natural sunlight or other forms of artificial lighting.  Determining the ideal distance to mount each LGM5 will require
some trial and error on your part.  We recommend that you begin by mounting the bars at the maximum
recommended height to allow plants to adjust to the quality wavelengths emitted from our LED grow lights and
then adjust according to your plant's reaction.

As a general rule of thumb:
Estimated coverage area as primary lighting for each LGM5 is a 30cm x 90cm area.  
As supplemental lighting (greenhouse or a room with access to sunlight) you are able to have approximately 45cm x 135cm of coverage.
